Jacobs Engineering Group Inc. (NYSE:JEC) has been selected by Minsur S.A., one of the world's largest tin producers, to perform the pre-feasibility and conceptual studies for the company's proposed tin mine development project in Peru. Both the conceptual and pre-feasibility studies are being undertaken to extend the life of Minsur's San Rafael tin processing facilities located near Puno, Peru.

The objective of the pre-feasibility study is to define the highest value option for accessing the richest tin zone in the proposed project location and will include structural geology, geotechnical services, hydrogeology and tunneling design. The conceptual study will include mine development, infrastructure, water management, metallurgical test support and upgrades to the existing concentrator to process tin ore that also contains copper and silver.

"Leveraging our 70 years of experience developing mining and metals projects, Jacobs delivers end-to-end project solutions to develop, expand and treat simple and complex ore bodies," said Jacobs Mining & Minerals and Specialty Chemicals Senior Vice President and General Manager Andrew Berryman. "The partnered facility expansion of this project will support sustainability efforts for future production."
